摘要： Why is Washington, D. C. the most important American city? Because . A. it is the largest city B. it is the largest in population C. it is the most beautiful city D. it is the capital of the United States C There is a definitepossibility that the climateof the world may be changing. Some scientists imagine that this could even mean the beginning of another ice age. The effects of such a change in climate on the human population of the world would be startling. Recent research suggests that the general warming trendof the past hundred years or so may be coming to an end. During the past ten years, meteorologists tell us the average temperature of the earth has dropped about one degree Fahrenheit. This does not seem like much, but it could have effects on wind and rain patterns which influence the overall weather picture. If these patternschange a lot, it could mean that certain regions of the world may continue to have long droughtswhile others will possibly suffer from widespread flooding. What regulatesthe climate is not exactly known. Meteorologists believe that clouds may be an important factorin regulating the amount of solarheat held by the earth, which in turn determines the temperature of the planet. Another possibility is that man’s industrial and agricultural methods may be affecting the natural weather patterns. However, the weather is not understood well enough for scientists to say for certain what is happening to the climate and what side effects this will actually have on the word’s population.

     Many Americans have been leaving their cars at home and riding to work on bicycles. They are
doing this because of gas prices, a slowing economy and concerns about the environment. Andy
Clark is the executive director of the League of American Bicyclists. His group supports bicycling
for fun, fitness and transportation.
     Mister Clark says this is good news for the environment. He says riding a bicycle to work does
not burn fossil fuel or create dangerous pollutants. Experts say the effects are the most important on
short trips. The Department of Transportation says fifty percent of Americans drive eight kilometers
or fewer to work. Shorter car trips release more pollution into the air for each kilometer driven. This
is because the device in a car that produces the harmfulness of emissions needs to warm up before it
can work well.
     Last year, the Pacific Northwest city of Portland, Oregon, had the highest percentage of bicycle
commuters(通勤者) in the United States. Portland has been doing progressive city planning for many
years to create special paths for bike riders.
     Andrew Land is one of Portland's citizens who bikes to work every day. Mister Land is thirty-three
years old and has never owned a car. He has biked to work for twelve years. Before moving to
Portland six years ago, he lived in Washington D.C. But he was hit by a car twice while biking to
work there. That has not happened in Portland where there are special; roads for bicycles. Mister
Land bought a house near these special bike lanes. He rides almost five kilometers to work each day
. He also uses the sixty-four kilometer bike path around the city.
     Andrew Land rides a cyclocross bike. He says it combines the best parts of a racing bike and a
mountain bike. You might say that Andrew Land is " into bikes". He recently attended a show of
handmade bicycle frames (结构). It was organized by thirty bicycle frame builders in Portland. And
he attended a legal rights workshop for bicyclists.

each kilometer driven"?

2. What can be inferred in the third paragraph?

B. The people in Portland are very poor
C. The traffic in Portland is very good
D. Cars are not allowed to run in Portland

3. Why Andrew Land was hit by a car twice while biking to work in Washington D.C?

A. Because he was too careless
B. Because there were no special paths for bike riders
